I'm being honest, I take your word for metal tones to heart because in our old SS Posse days, you knew how to get the tight shit. I honor you for that OG.
I tried out the free ToneX software, and I ended up buying ToneX and Amplitube within a few weeks. The ToneX software is very impressive. I dont have the pedal, but the pedals are basically just a player for what you tweak in the software.
I would download the free ToneX software, and see if you like it. You get 20 free downloads from Tone Net.
Bring the unit that you are most comfortable with. I would also recommend some clear plastic that you can tap over the unit to keep it dry. I played Sturgis in the late 90s. You’d be surprised by how much beer with end up on the stage.
